## Introduction |
|
|
|
In this project, we introduce "TIPO" (**T**ext to **I**mage with text presampling for **P**rompt **O**ptimization), an innovative framework designed to significantly enhance the quality and usability of Text-to-Image (T2I) generative models. TIPO utilizes the Large Language Models (LLMs) to perform "Text Presampling" within the inference pipeline of text-to-image generative modeling. By refining and extending user input prompts, TIPO enables generative models to produce superior results with minimal user effort, making T2I systems more accessible and effective for a wider range of users. |
|
|
|
## Usage |
|
Use updated version of DTG extension (renamed to z-tipo-extension), current version of z-tipo-extension support stable-diffusion-webui, stable-diffusion-webui-forge and ComfyUI. SD-Next haven't been tested. |

## Model arch and Training |
|
This model is LLaMA arch with 500M parameters, the training data is combined version of Danbooru2023, GBC10M and Coyo-HD-11M.<br> |
|
The total token seen is around 30B tokens.<br> |
|

|
|
|
*: We only count "non-padding token" in the token seen, since all the training data have very large length range <br/> |
|
`: Since the training data is pretty short, it cost more time to reach same token seen than general LLM pretraining.<br/> |
|
As reference, with 4096 as max ctx length and almost all the data have reach that length, you may only need 2days to reach 10B token seen on RTX 3090 x 4 with 200M model. |

### Evaluation |
|
We have tested TIPO in several metric: |
|
|
|
#### 1. Aesthetic Score (Higher is Better) |
|
|
|
We compute the Aesthetic Score using the **Aesthetic Predictor V2.5**. This metric is calculated on the short/truncated long test. |
|
|
|
 |
|
|
|
*Figure 1: Aesthetic Score distribution.* |
|
|
|
#### 2. AI Corrupt Score (Higher is Better) |
|
|
|
The AI Corrupt Score is obtained from the **AICorruptMetrics** in **sdeval**. |
|
|
|
This metric is calculated on the short/truncated long test. |

|
|
|
#### 3. Frechet Dino Distance (FDD) on Scenery Tag Test |
|
|
|
We use FDD on the Scenery Tag Test to demonstrate that when input prompts address a smaller distribution, the model struggles to generate images that reflect the true distribution. However, with **TIPO**, this issue is mitigated. |
|

| DinoV2 ViT-B | 0.2002 | **0.1755** | |
|
| DinoV2 ViT-L | 0.2017 | **0.1863** | |
|
| DinoV2 ViT-G | 0.2359 | **0.2096** | |
